Good Morning Amy,
I was writing to confirm that the lime clean up operation has been completed. I have attached a few pictures of the
primary area(s) of impact. I am still on site looking things over and I do not see any additional areas that need to be
addressed. With that being said, I respectfully request permission for crews to be able to return to work in full
capacity.

Amy,

I wanted to send a follow up email from our conversation earlier today. Crews are finishing up the lime cleanup
operation and are currently reinstalling EC measures. The project is still shut down and will remain shut down until all
EC measures are reinstalled and the project re-inspected. I am going out to the project tomorrow morning to perform a
re-inspection of the site and I will follow up with pictures. I am optimistic that everything will be cleaned up and
reinstalled by mid-morning. Like we mentioned in our conversation earlier today, we are having internal discussions
about the proper procedure to have project staff (Contractor / Sub-Contractor) removed from the project along with
conversations about the revocation of level 2 foreman who were in charge of management and oversite of the sub-
contractor’s performance. The following remedial actions were/are being taken in regards to the overflow.
Placed impervious dikes to isolate culvert water system and pumped contaminated water into
sediment basins
Removed contaminated water from the basins via water truck to dispose of
Flushed pipe system numerous times with clean water until pH values returned to normal levels (pH
currently 6.8 both up and downstream 200ft beyond the pipe outlet)
Replaced wattles downstream of system in case of contamination
Removal of all lime residue in checks/ditches/EC Measures on grade
Upon satisfactory completion of the above steps and with DOT approval impervious dikes will be
removed and normal function of the pipe system will resume
Additionally, the following steps will be taken moving forward as procedure for ensuring no spill of material will occur:
2 person confirmation that all gate valves have been fully closed and locks secured on Lime Tanker .
2 person confirmation that all in line valves have been fully closed and locks secured on hoses
between hydrant and the Lime Tanker (Slurry Pot) .
2 person confirmation that the water hose attached to the hydrant meter has been disconnected
from the meter.
2 person confirmation that the hydrant has been de-energized and locks placed on the valve
preventing water from being released at the hydrant .
Recording water meter reading at the end of each shift to ensure no water has run through the
system during the night.
Competent person will be on the ground monitoring closely any slurry placement near catch basins,
drop inlets or slope drains to prevent accidental discharge into those structures.
Additionally a FBDJV representative will sign off that these steps have been completed at the close
of each shift.
Once again, I apologize on behalf of the NCDOT, Flatiron & SitePrep for this occurrence. I, along with everyone else in
the Division very much appreciate you working with us while we get this issue resolved. I’ll follow up again tomorrow
once everything is 100% complete and reviewed.
Thank You,

Subject: U-2579DEF Onsite Lime Spill
All,
As many of you know, we have been performing soil stabilization operations for the last 6 weeks on the U-2579DEF
project. Our operation yesterday started at 7:00am and ended at 9:00pm. When the operation was complete, Site Prep
(Sub-Contractor to Flatiron) went through their standard procedures for cleaning and securing equipment before they
left for the night. One of their cleaning procedures is to fill their slurry tank (often referred to as a slurry pot) with fresh
water to prevent the tank from clogging up with residue. As usual, they connected the slurry pot to a nearby fire
hydrant to fill the tank. Apparently, Site Prep forgot to turn off the water before they left for the night so needless to
say, after the tank got full of fresh water, it came out of the overflow spout that is shown in the attached
pictures. When crews arrived on site this morning, they noticed that water was pouring out of the tank and running
down the grade and that’s when everyone was made aware of the situation.
We spent several hours out there this morning looking over the area and from what I can tell, a vast majority of the
slurry was captured on the grade and/or in the adjacent ditch lines. I did not notice any residual accumulation on the
rocks in the nearby stream, but some residue was noticed in ditch lines and rock checks on the grade. We instructed
Flatiron to obtain pH samples upstream, and downstream at 100’ intervals to determine if the lime had an impact on
the pH of the waters. The pH of the inlet was 6.8 and the pH of the outlet was 8.4. Flatiron will continue to review &
monitor the channel condition over he next few weeks and check the pH until it normalizes.
We do have slight lime residue in the pipe system that drains to permit site 8. We have installed impervious dikes at the
outlet of the pipe that flows into permit site 8 and we intend on flushing the pipe system, capturing all the water with
the impervious dike and pumping the water out and disposing of it properly.

Good Morning,
The above-mentioned project has had a lime spill overnight. This email is only to inform you that it happened, I don’t
have any further details at this time. I can give you more information once a site review has been done and I talk to our
folks.
Thanks
